|Red Giant Sun - NASA/Goddard Space Flight Center Conceptual Image Lab|
What would happen in 4 billion years when our sun begins heading toward supernova? Scientists theorize that our sun would grow in size and for a time become a red giant. These animations show the resulting effects on the planets of our solar system. Note: This animation shows the changing habitable zone as the sun expands to become a Red Giant.
